Wahlberg Bulks Up for "Pain & Gain"

Mark Wahlberg discusses the "huge physical transformation" he went through for his role in "Pain & Gain" and what it was like working with co-stars Dwayne Johnson and Anthony Mackie. (Published Tuesday, March 4, 2014)

As it happened, Johnson was MIA for last night's Hollywood premiere of his new action flick, the Michael Bay-directed "Pain & Gain" costarring Mark Wahlberg.

A rep for the 40-year-old thesp was unavailable for comment.

But news of the operation comes after Johnson got back in the ring earlier this month to take on rival John Cena at Wrestlemania 29, a title match he subsequently lost.
